The pumpkin is the king of fall, the fat lord of autumn, whose orange suit is summer’s last flame before winter’s darkness.

And, for 11-year-old KC Bellavance, two 50-plus-pound pumpkins are beacons of hope for kids with cancer.

Bellavance is a Fall River kid, but he spends a lot of time at Hassenegk Acres, the farm owned by his grandmother, Betsy Small.

“He’s here all summer,” Small said on a recent, damp day as she stood with KC in a field behind her home on Horseneck Road, close to the sound of the surf.

What KC Bellavance wants to do is not run a raffle.

“It’s an opportunity drawing," Small explained.

The difference between a raffle and an opportunity drawing is that an opportunity drawing requires less paperwork with the state, and you can get a ticket in an opportunity drawing without paying, though you are greatly encouraged to donate a buck (or more) per ticket.

Two lucky winners will each get one of the round, bright orange 50-plus-pound pumpkins currently resting on their sides in a field at Hassenegk Acres.

“They’re at least 50 pounds each,” Small explained, saying that, while they can’t weigh the pumpkins, Smalls knows she can pick up a 50-pound sack of grain but can’t pick up either of the pumpkins Bellavance is offering in the opportunity drawing.

Proceeds from the drawing will go to two charities for kids with cancer, one a fund dedicated to Westport’s Devin Laubi and another named after Fall River’s Haven Brooks.

“I said to him, 'Why don’t we find a local group?'” Small said.

Last year, Bellavance raised $111 for the Jimmy Fund, which helps children with cancer.

“It started off with me liking football and baseball, and I wanted to raise money,” Bellavance said.

People who want to get in on the win-a-pumpkin action can get tickets at Grum’s Restaurant on Charlotte White Road or at the Bayside on Horseneck Road.
